On one hand, the manual does talk about residual heating using the remaining engine warmth or warmth from the fuel in the vehicle to heat as FastLaneJB says, however, on the other hand it does allow A/C to turn on and also does mention that you should not do it in a garage and that the floor underneath the car will heat up so no loose flammable items there or they may catch fire...

So, it is described as independent ventilation / auxiiary heating in the manual and you can set it for a timer or for instant (while outside the car with the display key) or while in the car with some buttons.

I'll let you know whether it turns the engine on or not and how it works once i give it a go...always known about it but never used it!
All recent BMWs have ventilation when the car is off, and I believe you can set it on a timer, however if it truly has auxiliary heating then it won't need to start the engine, it will have a separate heater that is fuel powered that can independently heat the car without it running, I.e on cold mornings you can use that without having to leave the car running.

I think that's the case anyway. If it has it, great. If not, no big deal
